ARTHUR A. JOHNSON, OF WASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR TO UNDERWOOD TYPEWRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE.

MANIFOLDING.

Application filed September 11, 1920.

To all whom. it In (151/ concern Be it known that I, ARTHUR A. JoHNsoN, a citizen of the United States, and a resident of the city of \Vashington in the District of Columbia, have invented new and useful Improvements in Manifolding, of which the following is a specification.

This invention relates to manifolding and more particularly to the provision of means whereby the creeping of separate superposed webs is obviated.

In manifolding typewriting machines and other machines it has been found that. the webs, if made integral, will be maintained in proper superposed relation to one another, so that the writing lines on the upper-most sheet will properly register with the writing line on the lower sheets. That it is unnecessary to provide additional registering means for such a web, a fan-folded web for instance, is well known in the art. This, it is believed, is due to the fact that the webs are connected at one side edge and thus pass around or between cylindrical members, such as the platen and feed rolls of a rotary platen typewriting machine, as a single thick sheet would.

A typewriting machine capable of accommodating such fan-folded webs is illustrated 30 in the patent to Smith, No. 1,177,546, granted March 27, 1916. In this patented machine, the carbon sheets are interposed between the folds of the web and are carried by carbon arms mounted on a reciprocatory carriage, so that, after a form has been written upon and the platen swung upwardly sufficiently to permit it, the carbon sheets are shifted with respect to the web to the proper position with respect to the next form.

It is sometimes desired that the webs be separate from one another in the form of separate continuous strips and in this case usually some means must be provided for realigning the webs after each form is fed or during the feeding thereof.

The means of the present invention for obviating the creeping of the separate webs comprises a fan-folded fabric for embracing the separate webs of the pack. This folded fabric itself being fed without creeping, naturally prevents the creeping of the separate we, s which are embraced thereby. This folded fabric of the present invention may also carry the carbon for making carbon impressions on the separate superposed webs.

Serial No. 409,626.

If this is done the surface of each part of the folded fabric that lies directly above a worksheet is provided with the usual manifolding material.

A feature of this invention is also the provision of means by which the folded fabric carbon sheet may be attached to the reciprocatory carbon holder. This means may comprise a tongue on each leaf of the folded carbon sheet which tongue may' be wrapped around the usual carbon holding arm to be secured thereto by the usual clamp.

The folded carbon sheet is preferably fanfolded.

An additional fold may be provided upon the folded carbon sheet for the purpose of underlying the bottom web to include said web in its embrace.

The top web may under some circumstances be excluded from the embrace of the folded carbon sheet since the creeping between the other webs held in a pack by the folded carbon sheet and the top web would be slight, if any. Under some circumstances, however, it will be desirable to form the uppermost or original web integral with the web immediately below it and to have this lower web included in the embrace of the folded carbon sheet. If this is done, the web comprising the original web and the first copy Will have its fibres ruptured or will be provided with perforations at the fold to facilitate separation of the two parts thereof.

Other features and advantages Will hereinafter appear.

In the accompanying drawings;

Fig. 6 is a. view in cross-section of the folded carbon sheet and the webs inserted between the leaves of the carbon sheet.

In the Underwood fan-fold typewriter, a

webs, by

' however, and

platen 10, is mounted to swing upwardly and forwardly in order to permit the operator to straighten the course of the web or webs, so that the carbon sheet or sheets may be moved to a new position with respect to the web or the rearward movement of. a recip rocatory carriage 11, mounted to slide on a frame 12, which forms part of the typewriter carriage. The carriage 12 is provided with carbon carrying arms 13, each of which is provided with a carbon clamp 14. The mechanism, just referred to, may be substantially the same as that disclosed in said patent to Smith,

According to the present invention, the separate webs 15, and the web 16,-are embraced by a fan-folded carbon sheet, desig nated generally by the numeral 17. This carbon sheet comprises a part 18, a part 19, and a part 20 having carbonized faces 18 19 and 20, respectively, 15, and 15, respectively. The folded carbon sheet 17 is provided with an additional leaf 21 which underlies the lowermost web 15 and causes said web to be embraced between it and the part 20 of the carbon sheet. This part 21, being directly against the platen, when in the machine, is not carbonized on either surface. The uppermost web 15, is embraced between the part 20, and the part 19, while the web 16, is embraced between the part 19 and the part 18.

It will be seen that the separate webs are embraced by the folded carbon sheet and that they are thus held against creeping.

The original web 22 may under some circumstances be a separate web since the creep between the webs held in a pack by the carbon sheet 17 and the web 22 would be slight if any.

as shown in the drawings the web 22 and the web 16 are made integral and are connected at 23. Thus it Willbe seen that the web 16 being held in the embrace of the folded carbon. sheet, itself holds the web 22 against creeping. The folded web 16-22 is provided with a line of perforations 24 by means of whichthe arts 16-22 may be separated if desired. ach leaf of the folded carbon sheet 17 is provided with a tongue 25 by means of which the carbon sheet is connected to the reciprocatory carriage 11. Each of these tongues 25 is wrapped about a carbon holding arm 13 and secured in place on said arm by a clamp 14.

The tongues 25, are uncoated with carbon and are graduated in length, as shown in Fig. 4 or as shown in Fig. 5, to enable the use of carbon holding arms arranged as shown in Fig. 4 or Fig. 5, which show the carbon arms in stepped relation. Fig. 3 shows'the sheet 17 before folding, stripes being formed by the successive carbonized and uncarbonized portions.

In operation, the'platen 10 is swung upfor the webs .16, I

Under other circumstances,.

W'ardl from the full-line position to the dott'e -line position on Fig. 1, as more fully disclosed in said Smith patent, and the webs and carbon sheet, after being properly aligned, are placed around the platen of. the typewriting machine in the usual manner and the platen 10 is restored to its normal position. Aften the forms are Written upon, by the types 26 on type-bars 27, the leading edges of the webs which are slightly in advance of the carbon sheet, are grasped and firmly held by the hand of the operator. The platen is then swung upwardly to permit the operator to straighten the webs, the carbon sheet is shifted to a new position and the leading edges of the webs are brought to a suitable gage. The platen is then returned to normal position where it grips the carbon sheet and webs between it and the usual feed rolls, not shown; the webs being held firmly by the operator during the entire operation.

Variations may be resorted to within the scope of my invention and portions thereof may be used without others.

Having thus described my invention, I claim:

1. A manifolding assemblage comprising,

a fan-folded carbon sheet and a plurality of separate work-sheets embraced by said carbon sheet.

2. A manifolding assemblage comprising, a folded fabric, and a plurality of separate work-webs embraced by said folded fabric, whereby creeping between the work-webs will be prevented when the assemblage is fed around the cylindrical platen of a typewriting machine.

3. A mamfolding assemblage comprising, 7

a fan-folding fabric, a plurality of separate work-webs embraced by said fan-fold fabric, and a folded work-web having one leaf embraced by the fan-folded fabric, whereby creeping between the work-webs will be prevented when the assemblage is fed around the cylindrical platen of a typewriting machine.

4. A manifolding assemblage comprising, a fan-folded carbonized sheet, a plurality of separate webs embraced by said fan-folded carbonized sheet, and a folded work-sheet having'one leaf embraced by the fan-folded carbonized sheet.

5. A manifolding assemblage comprising, a folded fabric and a plurality of worksheets embraced by said folded fabric, said folded fabric having a carbonized face on each. of the leaves thereof that faces the working face of a work-sheet.
